This is a very interesting point!
When my friends are posting “AI generated” images they’ve prompted, on social media, I never think of them as the artist. I was extrapolating that to music. The differences in what’s generated/the type of results depend much more on the bot than the prompter. That’s assuming popular music generators will work like the image bots do (just type in a few words, get a track of music).
There’s an interesting example in the MB database where there’s a set of voice generated ‘characters’ that people use, and when they use them they credit them as artists, usually with ‘feat’ (even though the words have been written for them to ‘read’). Can’t find it atm… anyway, not the same, but related.
It will become clearer with time, but fun to theorize.
